Google have just posted on their official blog about ‘improving their privacy practices’.

One of these things involves so-called ‘anonymising’ their logs, which apparently involves:

We will change some of the bits in the IP address in the logs as well as change the cookie
information. We’re still developing the precise technical methods and approach to this, but we
believe these changes will be a significant addition to protecting user privacy.

Up until now, Google have just kept their logs for as long as they wanted – and in fact that isn’t going to change here. What will change is that 18-24 months afterwards, they will remove bits of the IP address and cookie information such that data won’t necessarily be tracable to one user any more.

Our engineers are already busy working out the technical details, and we hope to implement this new data policy over the coming months (and within a year’s time). We’ll communicate more as we work out these details, but for now, we wanted you to know that we’re working on this additional step to strengthen your privacy.

You can read a bit more in-depth about exactly what this anonymsing step is and involves in this PDF document.

So what is this? A PR stunt by Google to try and shake off some of the ‘evilness’ they’ve acquired in people’s minds (Google.cn, anyone?) or is a genuine attempt to try and protect Google’s users.

I think it’s mostly the latter. Google have been stubborn in the face of subpoenas before and this move would mean that it would be more difficult for legal processes to get their hands on data, but the time restriction also means that Google can do what they want with the data (and it’s also a compromise).

In fact, in a sense it kind of doubles as a PR stunt as well. If Google are subject to some kind of legal process that compells them to reveal data, they can turn around and say “well, we do this”.

Whatever it is, I’m all for Google being more transparent about how they operate. To me, this seems like a ‘good thing’.
